Objective To investigate the predictive value of neutrophil and lymphocyte ratios (NLR)for the prognosis in patients with acute cerebral infarction. Methods From January 2014 to December 2015,307 consecutive patients with acute cerebral infarction admitted to the Department of Neurology,the Fifth Affiliated Hospital of Zhengzhou University were enrolled retrospectively,including 80 females and 227 males. They were divided into ether a good prognosis group (n = 195)or a poor prognosis group (n = 112)according to the scoring criteria of the modified Rankin scale (mRS). The age,gender, past medical history,National Institutes of Health stroke scale (NIHSS)score were documented on admission. The NLR values were calculated according to the neutrophil and lymphocyte counts on admission. Logistic regression analysis was used to analyze the influencing factors of poor prognosis of acute cerebral infarction. The receiver operating characteristic curve (ROC)was used to evaluate the predictive effect of the NLR level on patients with acute cerebral infarction on admission. Results (1)Compared with the good prognosis group,the age,incidence of recurrent cerebral infarction,NIHSS score on admission, NLR levels on admission in the poor prognosis group were higher. There were significant differences between groups (69 ± 12 years vs. 62 ± 14 years,25. 0% [28 / 112]vs. 14. 4% [28 / 195],5. 00 [3. 00, 9. 00]vs. 3. 00 [1. 75,5. 00],and 3. 66 [2. 62,7. 91]vs. 2. 47 [1. 94,3. 40];all P < 0. 05). There were no significant differences in other baseline data and clinical characteristics between the groups (all P >0. 05). (2)Multivariate logistic regression analysis showed that the increase of the age,NLR level on admission,and increased NIHSS score on admission,were independent risk factor for poor prognosis (OR 1. 030,1. 148,and 1. 427,respectively,95% CI were 1. 007 -1. 053,1. 059 -1. 246,and 1. 247 -1. 634, respectively;all P < 0. 05). (3)The diagnostic cut-off value of the NLR level on admission for the poor prognosis in patients with acute cerebral infarction was 2. 84. Its sensitivity was 69. 6% and specificity was 64. 6% . Conclusion The increase of the NLR level on admission had certain reference function on the poor prognosis in patients with acute ischemic stroke.
